I have a Dell desktop with Windows 8 and it will wake up from sleep mode if not in use for awhile but if left for longer periods it goes into sleep mode and will not wake up. I have tried to wake it
Now it has started to download windows updates without installing them
The best I saved for last...it will not shut down it only goes into Power Save mode
very frustrating...suggestions please?

Was having this same problem and I fixed it. Check to make sure it's actually not waking! In my case the computer itself was waking but the display adapter was not. I could hear the processor fan come back on, the hard drives spin up, but nothing on my screen. In my BIOS, there was an option to not let the integrated graphics adapter sleep. It was called "RC6 Render Standby" and I turned it off -- fixed!
That might be a band aid. The sure fix is to update to the latest graphic drivers from Dell. I have an Inspiron 7000 also and was having this issue for about 2 months. When I received the Dell driver update about 3 weeks ago, this problem disappeared.
I too have a brand-new Dell Inspiron 7000 15 and had the same sleep problem right out of the box. I saw the answer above about turning off Intel Fast Start and tried it, and IT WORKED.
I then saw your answer Christopher and I went out and updated my graphics driver and then turned the Intel Fast Start back on, and problem SOLVED!!! thanks!
Just refreshed back to windows 8.0. Only thing that has worked on my Helix. Clearly 8.1 has an issue with many of these laptops.
I'm giving the Energy Star thing a try- hope it works, cause I'm REAL tired of this problem.
